3. Start a Niche Website – Earn from Affiliate and Google AdSense

Starting a niche website is one of the best ways to earn passive income for years. Multiple examples are out there who are still making money from sites, which they have not opened for years.

But why a niche website?

I could have recommended you start a blogging site and start earning by monetizing it from Google Adsense, however it would take you forever to get rank on relevant keywords and monetize.

When you target a specific niche, then it becomes much easier to get relevant traffic without much competition.

In a niche site, you must be helping people who are finding an answer to a particular question. For your understanding, I went through a case study that I would like to share.

The website Camper Report was started when its owner purchases an RV and build a blogging website around his experience. This site only writes content for the people who own an RV (that’s a super precise niche). With just 75 blogs post, Camperforce made $10,000 per month.

They majorly earn from Amazon Affiliate Program and advertisements.

Well, in niche sites you can earn from affiliate commission or advertisement that are one of the most comprehensive ways to earn.

How to start a Niche Website?

• Choose a particular topic (even better if you passionate about that) something like German Shepherd dogs – Not just pet dogs. This type of sub-niches would help you to avoid competition and increase your relevancy. (Learn: Find a Profitable Niche in 9 Steps)

• Shortlist topics to answer a specific query. Do not go for too broad issues with the new domain.  Google can help you a lot in finding clear-cut issues. Here is how,

Let’s say I start a male grooming website and want to write on “Beard Oil.”

Topic: Top 10 Best Beard Oils?….NO WAY!

It would take you forever to rank higher on Google with this topic. Instead, try to find out a more specific query. Go to Google and type your topic and add a random alphabet, Like here I wrote bread oil and added “a”

online business ideas for niche website topics

Tada! I found a great topic beard oil alternatives, which is somewhat less competitive, and I could easily find a product to promote and earn an affiliate commission on them.

If you have a budget, then I would highly recommend getting Ahrefs for content research and get better topic ideas.

• Get a wordpress setup and hosting (Bluehost recommended). Now, you need domain hosting to set up your WordPress blog. Check out this Free WordPress Blog Setup Guide.

• Search for a product to promote on your website and earn a commission. Amazon Associates and Aliexpress Affiliate Programs are absolutely free to sign up to become their affiliate marketer partners.

Other platforms to find affiliate products or services,

Make sure to plan the ideas of monetization before starting a niche website.  If you could find suitable products or services to promote on your website, then you could run an ad on your website for monetization.

In case you could not find an affiliate product within your niche, then you can still earn from advertisements by creating a Google Adsense account.

4. Instagram Account Flipping

Yes, this is an online business and a profitable one.

What is the Flipping Instagram account business?

Buy or create an Instagram account, optimize the account for some months, increase the followers, and sell it for higher prices. To get started with this online business idea, you need some smart working, automation, and knowledge of the topic of your Instagram page.

How to Start Instagram Flipping Business
